was kostet ein gentest für krebs — what can you do yourself?

The cost of a genetic test for cancer varies widely: direct-to-consumer (DTC) tests like 23andMe cost around $100–200 but only screen for a few risk variants (e.g., BRCA1/2). Clinical testing in many countries is covered by insurance if there is a family history (e.g., hereditary breast/ovarian cancer). What you can do yourself: schedule a doctor’s appointment for risk assessment, collect your family history, and consider genetic counseling. Self-administered tests without medical guidance often provide incomplete or misleading results – they are not a substitute for clinical diagnosis. Caveat: Evidence for DTC cancer tests is mostly marketing-driven; many variants have low penetrance. A positive self-test should always be followed by clinical confirmation and counseling.
